Get your taxes done using TurboTax

i dont have a printer and I'm being lazy. i realized that i should add my withheld refund in box 65 so it can be applied to what I owe them. so I was going to white out what is already there ( it is typed -- I did it on turbotax but then had to file by mail b/c of issues with my pin) and physically write in the new amounts. but i dont want to risk them rejecting it if it is partly written, partly typed. thank you!!
